The Babeltrace project provides trace read and write libraries, as well as a trace converter. Plugins can be created for any trace format to allow its conversion to/from another trace format.
The main format expected to be converted to/from is the Common Trace Format (CTF). The default input format of the “babeltrace” command is CTF, and its default output format is a human-readable text log. The “babeltrace-log” command converts from a text log to a CTF trace.
Trace Compass is a Java tool for viewing and analyzing any type of logs or traces. Its goal is to provide views, graphs, metrics, etc. to help extract useful information from traces, in a way that is more user-friendly and informative than huge text dumps.
